Wordpress LScache Plugin: Image optm hash does not match error ? quic.cloud
Last Updated on: Wed, 15 Apr 2026 00:00:02 Thanks for this note Stanley. https://wordpress.org/support/topic/solution-for-image-optm-hash-does-not-match-error/ Im getting this error when running LS image optimisation with quic.cloud enabled without object cache. Can you provide some guidance around the best settings to enable this to work. Will there be a fix (as above) in the near future ? Many thanks. Hi, Could you please provide the report number ? Best regards, Thanks for responding qtwrk Report No: PAYNCWIA Hi, Are you having some kind of security plugin , mod_security or firewall ? first time I access your site I got connection reset , and then I had to refresh it in order to load the page. this same happens to image optimization services , when it tries to fetch images , it hit error page , thus the operation will be stopped due to too many errors. Best regards, Apologies, I sent you the wrong report. That domain is actually working correctly with image op. Ive regenerated for one of the domains that is experiencing the issue. Report No: UAYXSCLY Im running WP Cerber Security and host has firewall (same setup on domain that is working fine). Only difference is quic.cloud is active on the domain that fails image op. Some additional information ? Ive made some DNS changes which may have not fully populated.

Ok, the culprit seems to be WP Cerber. Are there any IPs or Hostnames that I should whitelist for LiteSpeed & quic.cloud services ? Hi, Please check image server IPs from this list and Quic Cloud node IPs from this list Best regards,
